First of all its very handy to use, as it has 15.5 cm monitor screen and its quite look dashing than other brands.
Quality about this laptop is awesome as I have been using since month of April 2011 to now date 31/3/2017 which is nearly 6 years, in these 6 years I have not faced any hardware problems, yes I am not saying this is perfect and there is no issue in this but some issues can be ignored as its quality is awesome and its long lasting.
The only problem I have faced till now is right mouse button is loose and sometimes due to lack of servicing and high resolution game playing its getting heated sometimes.
Battery for this is awesome, in these 6 years I have not removed that battery and its durability now showing is 1.15 hrs
I have bought it with Rs. 31, 500 with graphics card including, but that money is clearly worth it for this 6 years service of Samsung laptop which I bought.
Service is awesome as I only taken it once to Samsung care for servicing and support is awesome as well as I had to install some drivers which is only for Samsung brand. They were very nice and they recommend me which driver to download.
I recommend all to buy this as you do not have to worry for external faults.
